COMBINED ICE AND SNOW SKATE.

Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed May 8, 1914. Serial No. 837,157.

To all whom it may concern:

Be it known that I, OLE F. CHRISTIANsEN, of Bedford, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Combined Ice and Snow Skates, of which the following is a specification.

This invention relates to skates and has for its principal object the provision of a skate which can be used with facility upon a hard surface such as ice or a relatively soft surface such as snow which is more or less packed.

A further object of the invention is to provide-a skate having fastenings which will adapt it to be firmly secured to any kind of a shoe whether provided with a rubber heel lift .or not. 7

With these and further objects in view the invention consists in the improvements which I shall now proceed to describe and claim.

()f the accompanying drawings, Figure 1 is a side elevation of a skate embodying my improvements, the snow runner being in raised position. Fig. 2 is aside elevation of the lower portion of the ice runner, with the snow runner adjusted to lower position for use. Fig. 3 is a plan view. Fig. 4 is a rear elevation with the parts in the relative positions shown in Fig. 1. Fig.5 represents a section on line 5 -5 of Fig. 1, omitting the runners.

Similar reference characters indicate similar parts in all of the views.

7 The foot plate as illustrated in the drawings comprises a toe section 10 and a heel section 11. The foot plate may, however, be otherwise formed and may be of metal or wood. Rigidly secured to the foot plate is the ice runner 12 which may be of any suitable form. Said runner is provided with slots 13 the lower ends of which are offset rearwardly at 14.

The snow runner 15 comprises two sections each having a vertical flange 16 bearing against the side of the ice runner 12. The flanges 16 have apertures for screws 17 which pass through the slots 13, and are provided with nuts 18, said screws and nuts servingas binding or clamping devices to hold the snow runner in any vertical position to which it may be adjusted. Since the screws 17 pass through apertures in the flanges 16, any vertical adjustment is caused to be equal with both of the sections of the snow runner.

When the skate is to be used upon ice the snow runner occupies substantially the posit1on shown in Figs. 1 and 4. When the skate is to be used upon snow or other soft sliding surface which would be out into too deeply by the ice runner, or if a person wishes to walk to the place for ice skating but is obliged to pass over a surface which would either injuregthe ice runner or into which the ice runner would out too deeply, then the screws 17 are loosened slightly and both screws are slid down the slots 13 andthen pushed slightly rearwardly. into the offset portions of the slots, and the screws are then again tightened. This places the skate in the condition illustrated in Fig. 2 with the snow runner substantially flush with the lower edge of the ice runner. .When a person is wearing a pair. of skates having the snow runners in substantially the position shown in Fig. 2, quite rapid progress may be made over packed snow or over snow that is not too soft by a movement somewhat similar to roller skating. Or the skates may .be used for coasting when in the condition illustrated in Fig. 2.

In order that the skate may be worn with practically any type of shoe, I provide fastening means which I shall now proceed to describe :The front portion of the section 11 of the foot plate is slotted at 19 as indicated by dotted lines in Fig. 3. A screw 20 passes vertically through said slot and is provided with set nuts 21. The head 22 01 the screw is irregular as to its margins as indicated in Fig. 3 so that by turning the screw .a difierent portion of the head 22 thereof may be employed to bite into the front or breast of the heel of a shoe. Owing to the fact that the head 22 is offset or projects from one side farther than from another side, the positioning of the screw as described presents a binding edge which is at a greater or lesser distance from the rearmost clamping member presently described according to the size of the heel, that is to be gripped. Owing to the provision of the screw and nuts 21, the head 22 may be set at such a height as may be nec ssary-t0 best engage the breast of a'heel. In Fig; 1* the heel of the shoe is represented as having passes horizontally, said screw having. a

.plate'25 swiveled to its front 'end said plate having a biting flange 26 and alsoia trio-- tio'n pad 27 The screw 24L engages and passes 'throiigh an internally threaded bolt 28 the outer sides of which arefiattehed to engage the walls of the slot of the upright 23 so that said bolt cannot rotate in "said slot. The head 29 of the bolt engages one side 0 f the'upright 23'and' a set nut 30 fitted l to an ex ternalwportionofthe bolt 28 engages the other side of the upright- 23. By means of the nut 30 the halt 28 may "be secured in proper vertically adjusted position to 'meet the requirements of any shape and height or heel, and the screw 24L may be'rotatetl by means of a wreneh engaging its outer end so as to force the hithl'g flange 26 or the friction pad 27 ag inst therearof the heel ofashoe, thereby co-actihgwith the front gripping member 22 in seturi g the skate to the 'shoe' heel. Owing tefithe swivels-d connection of theplate- 25 with the inner end eithe -screw 24:, said plate 25 may be otated 'so thateitherits biting flange 26', or-the f'rietion'pad 27,1h'ay bear againstthe rear ofthe sho heel.

The the straps 31 are pivotally connected at 32 to the section 10 of the foot plate;

Eaehfs tra'p is provided with an adjustable sole edge gri per 3 3 which consists "ofa meta1h6p1ate haying lips 34 'Whichemhraee the strap section. As indicated in Fig. 5 thememherseaareef an angul'arshap te fit the edges of a "shoe sole. Owing to their angular formation and the lips 34 which extend around the edges of the strap, the membersse cannot'slip. Thetwo strap sections maybe'conneted by stiitable b'u'hle 35. Preferably the pivoted ends of the Strap sections fit an depressions 36 in the plate 101 Many skaters do not like to rely solely upon sole edge'grippers-heeause unless the shoe fits very hghay there' i's net the same feeling "of security as when a toe'str'ap is 7 employed. The ordinary toe strap, however, permits the'foot to shift laterally across the the iportion of the foot 'plate. By my improved attachments 83, the foot is prevented from slipping sidewise. Owing to the pivotal cohne'ction'of the'strap section with-the foot plate the-straps can "be swung so that the grippers 33 will engage the side edges of the sole of "a shoe firmly, without marring the same, no matter whether the sole is more 7 that theprong 37 will bite thereinto".

In Fig. l 1 have indicated by dotted lines the lower portion at a shoeto which'the skateis attached. As illustrated in 'said fig ure the biting flange 26 enters the'reeessor groove at the top 05E the heel at the shoe whne therhetieapaaa'zteaas heart against 'therear'of theheel. Aswill be readily 1inclerst'o'otl the adjustahility 0f the rearheel clamping member enables it to be so-mouth ed asto' engage the p'ortihn'ot the heelhidicated-in-Ftg. 1, thereby avoidih a y nrarring whatever ot-therear of-the heel.
